Description
Technical Field
The utility model relates to the technical field of pressure sensor elastomers, in particular to a pressure sensor elastomer.
Background
The strain type pressure sensor is a common pressure sensor, the working principle of the strain type pressure sensor is that the pressure is measured by utilizing the strain generated when a material is stressed, the elastic body is a substance which can be deformed by the action of external force, when the external pressure acts on the strain type pressure sensor, the elastic body is strained, the resistance value of the induction resistor is changed, the change is converted into voltage change, and the magnitude of the external pressure can be obtained by measuring the voltage change.
In general, a stress area in a strain type pressure sensor is closely attached to an elastomer, and after the stress, the elastomer can receive the pressure of the whole stress area and cannot receive the pressure of a designated position, so that the pressure sensor elastomer is provided.
